Materials Data on CsAuO by Materials Project
CsAuO crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Cs1+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent O2- atoms. There are two shorter (3.08 Å) and two longer (3.17 Å) Cs–O bond lengths. Au1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Au–O bond lengths are 2.06 Å. O2- is bonded to four equivalent Cs1+ and two equivalent Au1+ atoms to form a mixture of edge and corner-sharing OCs4Au2 octahedra. The corner-sharing octahedra tilt angles range from 4–8°.
